Burners from technical ceramics
Burners from technical ceramics in constructions of gas furnaces and fuel industrial furnace
Burners from technical ceramics have been successfully proved in constructions of gas furnaces and fuel industrial furnaces with liquid fuel (for example, burners of impulse type and recuperative burners), and in households. Burners from technical ceramics are also used in the process of “indirect heating” when combustion gas should not contact with product. For example, the flame tubes, radiation tubes that conduct heat through radiation.

Advantages:
Reaction sintering silicon carbide burner is an ideal burner for tunnel kiln, shuttle kiln and roller kiln. It is also widely used in industrial furnaces with open fire direct heating system and radiant tube indirect heating system.
Reaction sintered silicon carbide heat exchange tube, inner tube and outer tube of reaction sintered silicon carbide radiant tube are assembled for heat radiation indirect heating system. Reaction sintering silicon carbide indirect heating system is suitable for steel, stainless steel and non-ferrous metal industry roller kiln, trolley kiln and other industrial furnaces.
SiC atomizing nozzle is the key part of flue gas desulfurization and dust removal equipment in thermal power plant and large boiler. It has been widely used in desulfurization and dust removal devices of thermal power plants and large boilers.
